Under ESOS, large UK organisations are obligated to carry out ESOS energy assessments before the deadline of 5 December 2015, using one of four compliance routes:
- ESOS Energy Audit
- ISO 50001 Certification
- Display Energy Certificates
- Green Deal Assessments.
By the deadline, qualifying organisations must have carried out their energy assessment(s) and notified the Environment Agency (EA). The assessments must then be repeated at least once every 4 years.
If an organisation has a UKAS-accredited ISO 50001 certificate that covers the full scope of ESOS, then that will suffice as ESOS compliance. All organisations need to do then, is notify the EA and provide proof of compliance via that route.
However, if ISO 50001 is not used as a route to compliance, then an ESOS energy audit will be needed as the next best and most common available route to compliance.
What happens after 5 December 2015?
Every four years, a new compliance period starts. The qualification date for compliance Period 2 is 31 December 2018, with proof of compliance covering the period (from 6 December 2015 to 5 December 2019) being required by 5 December 2019.
If your organisation chose an ESOS energy audit as the compliance route for Period 1 then you will now have a robust ESOS evidence pack that will include:
- the calculation for your total energy consumption
- a list of your identified areas of significant energy consumption
- details of the energy saving opportunities identified.
However, you won’t be able to use this information to demonstrate Period 2 compliance, so this exercise will need to be repeated in four years’ time.
Alternatively, information from your first ESOS energy audit can be used as the basis for implementing an energy management system (EnMS) to allow realisation of the energy saving opportunities.
If your system is then certified to ISO 50001 during the next four years, your organisation will automatically demonstrate Period 2 ESOS compliance.
Benefits of implementing ISO 50001 to demonstrate Period 2 compliance
- You are assessed regularly for continual improvement in energy efficiency, so you continue to reduce costs, meaning that ISO 50001 saves you money
- Your EnMS gives you a tried and tested strategic framework and long-term plan for energy saving, which has to have top management support and engagement
- You minimise risk and increase energy security through rigorous auditing
- Your EnMS certification can give you a competitive edge, through improved environmental performance, productivity, compliance and communication of best practice.
By choosing ISO 50001 certification as your route to ESOS compliance, LRQA can offer a range of solutions to help.
